Yes -- have you not seen the size of SD cards these days?  An R for 
Windows install is under 50Mb and needs about 12Mb RAM to run.

That was not the question.

But that was.  However, as I said, you would have to find a suitable 
compiler or cross-compiler, that supports enough features (and I suspect 
IEEE arithmetic would be a problem, especially as it is for VC++ on full 

Perhaps you would like to write such a compiler, as technically there's 
not much to stop you?

I think you are belittling the work done to get R running on as wide a 
range of platforms as it does.
